Top 12 Site Reliability Engineering Tools

SRE as a Service


All application and infrastructure elements such as servers, databases, and networking equipment create logs, metrics, and traces that hold important information about the health of the IT environment. As organizations grow in size and complexity, IT environments also expand, leading to exponential growth in their data volumes. Reliable management and real-time monitoring of logs, metrics, and traces help optimize this extended environment. It also provides insight into various performance issues and errors affecting various IT equipment and applications. Therefore, it allows you the opportunity to analyze past data, detect anomalies or outliers, and predict future trends.

Looking into the health of the system, identifying the application issues, tracking the complete end-to-end flow of a request, and dubbing issues require site reliability engineers. The goal of site reliability engineers is to maintain system resiliency by promoting the good health of ongoing operations and the availability of production systems. To do their job efficiently, these engineers rely on a number of Site Reliability Engineering Tools. However, not all organizations follow all the practices related to site reliability engineering. Therefore, site reliability engineers can have multiple roles and responsibilities. But the thing that remains common for all SRE engineers is the use of advanced tools to improve service delivery.

This blog will explore the top site reliability engineering tools available in the market and serve different use-cases in categories such as monitoring, communication, incident response, and configuration management.

APM or General Monitoring Tools

Application performance monitoring tools are important as these provide real-time performance insights allowing SRE engineers to react fast when issues arise. Observability is collecting raw, granular data necessary to gain an in-depth understanding of complex and distributed systems. APM tools provide visibility to work on issues to reduce mean time to resolution and restore applications to normal performance.

1. Datadog

Datadog provides monitoring and observability service for servers, databases, tools, and services for cloud-scale applications through its SaaS-based data analytics platform. It allows you to keep track inside any stack, any app, at any scale, and anywhere. Even Gartner has recognized Datadog as the best APM tool in Gartner Magic Quadrant due to its impeccable features, including:

  • See across systems, apps, and services

Automated Incident Response Systems

An automated incident response system refers to the process and methodology used to implement a systemic and calibrated response to security breaches. It allows site reliability engineers to respond to incidents in real-time and troubleshoot issues if they occur to prevent business continuity. As the team deals with overwhelming levels of data when an alert is raised, they use some tools to identify triggers behind the incident and plan a complete postmortem to avoid future impact.

6. Grafana

Grafana is popular for its powerful visualization and alerting mechanism. It is also considered among enterprises having specific privacy or security requirements and needing a self-managed environment. With Grafana as your SRE tool, you can create, explore and share all of your data through beautiful, flexible dashboards. It is one of the best observability tools to seamlessly switch between metrics, logs, and traces. Here are some of the top features of Grafana:

Configuration Management Tools

Site reliability engineers use configuration management tools to keep track of changes to applications and infrastructure resources for faster application delivery. However, they employ multiple tools in their tool bucket to meet different requirements of the project. The widely adopted tools worldwide include:

10. Terraform

Terraform is an open-source infrastructure as code software by HashiCorp. It allows users to safely and predictably create, change, and improve infrastructure by provisioning both low-level components, such as storage and networking, and high-level components, like DNS entries, and SaaS features. It uses declarative templates to automate the provisioning of any infrastructure resource, including virtual machines, applications, and Kubernetes clusters on both on-premises or in public cloud environments.

Terraform is one of the widely adopted Infrastructure As Code tools. You can learn more about the benefits of Terraform for IaC in cloud and DevOps and improve your day-to-day development and deployment processes.

11. Ansible

Ansible is an IT automation engine widely adopted in project development to automate time-consuming, complex, and repetitive tasks. It uses YAML configuration files to define roles and tasks and orchestrate their execution in a specified order across multiple infrastructure components. Ansible uses SSH keys to connect to relevant machines and runs the playbook defined in the YAML files. Ansible is based on Python and allows customization based on varied use cases.

12. SaltStack

Being a configuration management and orchestration tool, SaltStack automates repetitive system administration and code deployment tasks, reducing manual process errors. Being SRE tool, it uses a different method of infrastructure automation since it deploys agents on compute notes and performs orchestration by pushing commands to the node. SaltStack scales up to thousands of nodes with very low overhead.


Site reliability engineering tools enable enterprises to create and support scalable and highly reliable software systems. SRE is significant in organizations that have jumped to cloud-native applications and distributed computing. By using the right tool and employing them in the right process, it is possible for organizations to perform preventive maintenance and keep the cloud infrastructure always up.
